Windsor police made their presence known at the city’s Via Rail station today, after an announcement the rail line was ramping up security following an "unfounded threat."

Via Rail says it has increased police and canine patrols in certain train stations.

Many Windsor passengers traveling to Toronto on Wednesday say they are favour of the additional surveillance.

A spokesman for the passenger rail company says a threat was received recently and police were informed, but it appeared to be unsubstantiated.

Spokesman Malcolm Andrews says Via has nonetheless reminded employees to be vigilant and has increased patrols at some stations.

He says Via is also working closely with law enforcement.

The railway notes that passenger transportation companies around the world have been the target of unsubstantiated threats "for some time now."
